Hi, I would like to calculate the rotational speed of a wind turbine with a power of 20 kw and average wind speed of 9 m / s. I want to know if there is a formula or a specified range. View
Blade pitch control is a feature of nearly all large modern horizontal-axis wind turbines.It is used to adjust the rotation speed and the generated power. While operating, a wind turbine's control system adjusts the blade pitch to keep the rotor speed within operating limits as the wind speed changes.
Average power output will be roughly about twice the instant power output at that windspeed (assuming that the wind varies according to the Rayleigh distribution aka k=2). Instand power in theory is 1/2 x density of air (1.2) x area x windspeed cubed = .5 x 1.2 x 9 x 27 = 150 watts or so average (3 m/s wind)
Wind Energy Science is an international scientific journal dedicated to the publication and public discussion of studies that take an interdisciplinary perspective of fundamental or pioneering research in wind energy.
Jan 24, 2009 · Efficiency in Extracting Wind Power Betz Limit & Power Coefficient: • Power Coefficient, Cp, is the ratio of power extracted by the turbine to the total contained in the wind resource Cp = Pto the total contained in the wind resource Cp = P
The total wind power flowing into the turbine is defined by the fairly simple wind power formula, shown to the right. The power into the turbine blads is a function of the wind speed to the 3rd power (V times V times V), air density, and swept area of the turbine blades. A simple version of the wind power formula is shown to the right.

If your wind generator rotor is operating at a low TSR compared to the optimum value, then your wind turbine’s blades will tend stall before hitting maximum power/efficiency. If the wind turbine’s blades are spinning above the recommend TSR, then the blades will be traveling through turbulent wind.
based on soft-computing methodologies, such as artificial intelligence and genetic The output power of the turbine is given by the following equation: (λ, β)(1) Where ρ is the air density, A is the turbine swept area; v is the wind speed and the power coefficient Cp.
